Silhouette art of a girl staring at something

Hello everyone
Greetings to you all
I been a while i work on my new art concept called silhouette. I figured out that it's proper to put this concept of art here on hive since there's nobody that is working on it.
Silhouette is a concept of drawing that involves the use of all-black to creat an art. But since it's limited to some photos, i decided to make my art 80% silhouette in order to make it a bit photorealistic.
I used a charcoal pencil and cardboard paper alone to create this art.

Progress

Thank you for viewing my art.
